Abstract: 1287401 Grippers for lifting coils WELLMAN CRANES Ltd 18 Aug 1969 [17 May 1968] 23577/68 Heading B8H A gripping device, Fig. 1, for handling rolls of strip 52, has power-operated means for tilting the device through substantially 90 degrees about a horizontal axis and coupling means between the clamping jaws 28, 14 and the tilting means arranged to automatically vary the force exerted by the jaws as the device is tilted. As described the movable jaw 28 is driven into engagement with the roll 52 by a screw and a motor 34. Tilting is effected by winches and cables attached to links 17, 21. The jaw 28 is mounted so that movement of a pin 18 in an arm 16 between stops 35, 36 on the jaw 12 causes the clamping force to be increased as the device is tilted to a position in which the opening between the jaws faces downwards. In a second embodiment, Fig. 5, the device is pivoted to the forked end 53 of a mast 54 for tilting about a horizontal axis 55. The jaw 28 is carried on a piston-rod 61 slidable in a cylinder formed in the arm 13 of the hook 12. The upper end of the rod engages the lower surface of a toggle arm 57. The jaw 28 is initially moved into engagement with a roll 51 by the piston-rod 61 and when the device is tilted by a ram 59 the toggle arm 57 turns about its pivot 56 and presses on the end of the rod 61 to increase the clamping pressure. Fig. 8 shows a further embodiment in which the jaw 28 is moved by a screw 31 and a motor 34. The device is rotated by a quadrant 83 driven by a pinion 82 and the clamping force is increased by a parallelogram linkage. In a fourth embodiment, Fig. 12, which is generally similar to that shown in Fig. 8, an hydraulic cylinder 101 moves the jaw 28 and a pair of cylinders 100 pivot the device. A further cylinder 102, which is hydraulically connected to the cylinder 101, increases the clamping force as the device is tilted.

Abstract: 442,679. Automatic control of electromotive force, current, &c. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and GIBSON, J. W., c /o General Electric Co., Ltd., Witton, Birmingham. Aug. 17, 1934, No. 23754. [Class 38 (iv)] Over regulation and hunting is minimized in an automatic regulator of any quantity, for example, voltage, by causing raise and lower contacts to co-operate with a contact or contacts which is or are displaced against a biassing force through the contact pressure, and retarding the return of the co-operating contacts to normal positions by damping means. The raise and lower contacts may for example control a resistance in the field circuit of a generator in the manner shown in Fig. 3 of Specification 322,510, [Class 38 (iv)]. The invention is described with reference to the control of the voltage of an alternator 17 and an induction disc relay responsive to its terminal volts and compounded by a current transformer 25 operates a single contact 1 mounted by a spring 4 on the spindle of the relay. Raise and lower contacts 2, 3 are carried by a separate spindle 6 and biassed to a normal mean position by a spring 13. When contact is made by the contact 1 the contacts 2, 3 are displaced but their return is checked by the damping magnet 32 operating on the spindle 6 in the manner shown, so that the engaged contacts become separated and contact may be made between the other pair if the regulating effect be too rapid. Other applications of the invention mentioned are the control of the voltage of a D.C. machine and of the current of A.C. and D.C. machines.

Abstract: 833,455. Transformers. RADIO CORPORATION OF AMERICA. Aug. 1, 1956 [Aug. 10, 1955], No. 23787/56. Class 38 (2). A magnetic device of the transfluxor type, comprises a magnetic core having a " square loop " characteristic which is provided with a first aperture 12 through which a blocking winding 18 passes so that a pulse through this winding fully saturates the core around the aperture, i.e. blocks the device; a second aperture 16 defining legs 3 and 4 being provided with input and output windings 28, 30 linking leg 4, and a third aperture 14 defining legs 1 and 2 being linked by a setting winding 24. A positive pulse through winding 24 reverses the flux through legs 2 and 3 thereby unblocking the device, e.g. allowing transformer action between windings 28, 30 for pulses 42, 40 by virtue of flux changes immediately around aperture 16. A subsequent negative pulse through winding 24 reverses again the flux in leg 2, thereby decoupling this winding so that further pulses in this winding do not affect the other windings. A winding 36 linking leg 3 may be fed with positive pulses as an alternative to the negative pulses 40 on the winding 28. In a modification (Fig. 4, not shown), each small aperture is linked by a pair of windings, either pair acting as the input and output windings whilst one of the other pair acts as the setting winding.

Title: Improvements in coin freed mechanism for use in combination with automatic weighing apparatus
IPC: G07F17/04
Filed: 1924-10-09
Abstract: 245,220. Avery, Ltd., W. & T., and Bradley, L. C. Oct. 9, 1924. Indicating-mechanism.-In weighing-apparatus in which the indicating-mechanism is freed after the application of the load by insertion of a coin, the indicating mechanism is operated through a toothed member which is actuated by the release of energy stored in a spring coupling it to the resistant mechanism during the application of the load, the release of the energy being effected by a coin, and both the disconnection of the toothed member from the resistant mechanism and the return of the indicating mechanism to zero being effected by the removal of the load. As applied to a machine having pendulum resistants 37, Fig. 1, and an indicating-finger rotating over a graduated scale, the rotation of the finger is effected by a rack 12, engaging a pinion 10. The rack is partly disposed within a tube 13 and is surrounded therein by a spring 14, Fig. 4, abutting against the tube and a plunger 15. It is connected to the plunger 15 by a pawl 17 held in engaged position by a magnet 18 and a spring 19. When a load is applied the pendulums 35 move the tube 13 upwards, the spring 14 being compressed, since the rack is prevented from moving by a finely toothed wheel 23 on the spindle 11 of the indicating-finger being held at zero by a fixed tooth 24 on a lever 26.The lever 26 is connected by a rod 28 to a counterweighted coin lever 29 which tilts under the control of a dash pot 31, when a coin is inserted in a bucket 30, and disengages the tooth 24. The rack, controlled by a dash pot 22, is then moved up by the spring 14 to indicate the weight, the indicating-finger being locked in this position by a second tooth 25 on the lever 26 engaging the locating wheel 23, thereby preventing any addition to the load from being indicated. A gravity rod 20 secured to the heel of the pawl 17 is carried upwards with the rack away from a lateral support on the lever 26, and, when the load is removed and the downward movement of the tube 13, removes the magnet 18 from its major attractive position relative to the pawl, this rod disconnects the pawl and rack from the plunger 15 and hence from the weighing mechanism. The removal of the load causes the levers 29, 26 to return to normal position and release the wheel 23, thereby allowing the rack to descend and return the indicating finger to zero. The pendulums 37 are positioned at their zero position by means of two magnets 38.
